A Facile Synthesis of 1,3-Dihydro- isobenzofurans Using Iodocylization of 2-Vinylbenzyl Alcohols
摘要:
An efficient route for the preparation of 1,3-dihydroisobenzofurans based on the iodine-mediated cyclization of 2-vinylbenzyl alcohols, which can be prepared feasibly by reactions of 2-vinylphenyllithiums with carbonyl compounds, is reported. Substitution reactions of the iodo moiety of the resulting 1-(iodomethyl)-1,3-dihydroisobenzofurans with tributyltin hydride and sodium thiolates are also described.
